To investigate the effect of COVID-19 pandemic on frequency various crime types (property, violent, and mischief) in Vancouver, Canada.Crime data representing residential burglary, commercial theft vehicle, from theft, violence, mischief are analysed at city level using interrupted time series techniques.While has not had an impact all types, statistically significant change been identified a number cases. Depending type, magnitude direction varies. It is argued that (mandated) social...
We demonstrate nanoscale resolution in far-field fluorescence microscopy using reversible photoswitching and localization of individual fluorophores at comparatively fast recording speeds from the interior intact cells. These advancements have become possible by asynchronously photon bursts molecular switching cycles. present images microtubular network an mammalian cell with a 40 nm.
Dronpa is a novel GFP-like fluorescent protein with exceptional light-controlled switching properties. It may be reversibly switched between on-state and nonfluorescent off-state by irradiation light. To elucidate the molecular basis of mechanism, we generated switchable crystals. Using these crystals determined elusive dark-state structure at 1.95-A resolution. We found that photoswitching results in cis-trans isomerization chromophore accompanied complex structural rearrangements four...
Proteins that can be reversibly photoswitched between a fluorescent and nonfluorescent state bear enormous potential in diverse fields, such as data storage, vivo protein tracking, subdiffraction resolution light microscopy. However, these proteins could hitherto not live up to their full because the molecular switching mechanism is resolved. Here, we clarify photoswitching of asFP595, green (GFP)-like transferred from “off” “on” back again, by blue light, respectively. To this end,...
RSFPs (reversibly switchable fluorescent proteins) may be repeatedly converted between a and non-fluorescent state by irradiation have attracted widespread interest for many new applications. The RSFP Dronpa switched with blue light from into state, back again UV light. To obtain insight the underlying molecular mechanism of this switching, we determined crystal structure equilibrium Dronpa. Its bicyclic chromophore is formed spontaneously Cys62-Tyr63-Gly64 tripeptide. In it adopts slightly...
This paper investigates the spatial aspect of criminal activity in Vancouver, Canada, employing social disorganization theory, routine theory and multiple measures crime. Crime counts crime rates with residential ambient populations as denominators are calculated using calls for service made to Vancouver Police Department. The population—a 24-hour average estimate a population unit capture at risk—is obtained from LandScan Global Population Database resolution relevant criminological...
Recent research in the ‘‘crime at places’’ literature is concerned with smaller units of analysis than conventional spatial criminology. An important issue whether patterns observed criminology focused on neighborhoods remain when shifts to street segments. In this article, authors use a new point pattern test that identifies similarity patterns. This local nature such output can be mapped showing where differences are present. Using test, investigate stability crime moving from census...
This article investigates the spatial dimension of automotive theft, break and enter, violent crime in Vancouver, British Columbia 1996. The uses synthesizes social disorganization theory routine activity as a theoretical backcloth employs autoregressive regression procedure that accounts for autocorrelation between rates socio‐economic characteristics at census tract level. Strong support is found synthesizing these two most common theories crime. In particular, high unemployment (social...
Crime rate is a statistic used to summarize the risk of criminal events. However, research has shown that choosing appropriate denominator non-trivial. Different crime types exhibit different spatial opportunities and so does population at risk. The residential most commonly risk, but unlikely be suitable for crimes involve mobile populations. In this article, we use “crowd-sourced” data in Leeds, England, measure considering violent crime. These new sources have potential represent...
Abstract This article uses an alternative measure of the population at risk, ambient (provided by Oak Ridge National Laboratory), in crime rate calculations. It is shown through a variety statistical analyses two different scales aggregation that this alternatively calculated not always related to conventionally rate. The implications finding are past theoretical testing and policy formation might have been based on spurious results, showing importance remaining current with developments...
It is well known that, due to that inherent differences in their underlying causal mechanisms, different types of crime will have variable impacts on groups people. Furthermore, the locations vulnerable people are highly temporally dynamic. Hence an accurate estimate true population at risk a given place and time vital for reliable rate calculation hotspot generation. However, choice denominator fraught with difficulty because data describing popular movements, rather than simply residential...
Crime analysts need accurate population-at-risk measures to quantify crime rates. This research evaluates five find the most suitable ambient estimate for ‘theft from person’ crimes. Collect ‘ambient’ datasets: 2011 Census, aggregate mobile telephone locations, and social media. Correlate population against volumes identify strongest predictor. Use Gi* statistic statistically significant clusters of under alternative denominators. Explore locations clusters, comparing those that are...
